PyCharm导入cuda模块报错No module named 'cuda._lib'，终端可正常运行求助

问题现象 #

• 按照CUDA-Python官方文档的conda安装步骤完成安装后，在PyCharm的Python控制台执行代码from cuda import cuda, nvrtc时触发错误：

Traceback (most recent call last):
  File "D:\Anaconda\envs\hierot\lib\code.py", line 90, in runcode
    exec(code, self.locals)
  File "<input>", line 1, in <module>
  File "D:\PyCharm Community Edition 2022.1.3\plugins\python-ce\helpers\pydev\_pydev_bundle\pydev_import_hook.py", line 21, in do_import
    module = self._system_import(name, *args, **kwargs)
  File "cuda\cuda.pyx", line 1, in init cuda.cuda

    module = self._system_import(name, *args, **kwargs)
ModuleNotFoundError: No module named 'cuda._lib'; 'cuda' is not a package

• 但在Anaconda终端的hierot环境中执行相同代码却能成功运行：

(hierot) D:\Projects\SimPlatform>python
Python 3.9.13 (main, Aug 25 2022, 23:51:50) [MSC v.1916 64 bit (AMD64)] :: Anaconda, Inc. on win32

>>> from cuda import cuda, nvrtc
>>>

已尝试的无效方案 #

• 搜索ModuleNotFoundError: No module named 'xxx'相关方案，尝试重新配置PyCharm的Python解释器，未解决问题。
• 搜索No module named 'xxx'; 'yyy' is not a package，得知可能是cuda名称被遮蔽，但不清楚具体修复步骤。
